GRAIN-'CAR DOZVOR.

SPECIFICATION forming part of Letters iatent No. 589,198, dated August 31, v1897'.

Application filed October 1 2, 1 896,I Serial llo. 603,688. (No model.l

I Vand has for its object to provide a doorof this character which will be perfectly7 grainftight',

durable, and capable of being easily operated,

which will take up a minimum amount of space and be out of the way when not in use, and which has provision wherebyit may be securely locked in either itsope'rativegor iny operative position.

Other objects and advantages of theinven- Vtion will appear in the course of the ensuing description. l

The invention consists in certain novel features and details of construction and arrangement of parts, as hereinafter particularly set forth, illustrated in the drawings, and embodied in the claims. j

In the accompanying'drawings, Figure l is an interior perspective view of a port-ion of'a box-car, taken adjacent to the door-opening and showing the improved grain-door and the manner of mounting the same. Fig. 2 is an enlarged horizontal section through 'the door and its keepers. Fig. 3 is a vertical section through the door and a portion of the cariioor. Fig. 4 is a perspective view of the cardoor detached, taken fromthe inside and showing the top edge thereof. Fig. 5 is a similar view ofthe car-door, takenfrom the outside and showing the bottomedge of the door.v

Similar numerals of reference designate c orresponding parts in the several Iigures of the drawings.

The grain-door contemplated in this invention is 'vertically slidable and removable and is wedge shaped. In other words, theside edges of the door (indicated at l) converge toward the bottom edge of the door, so that as soon as the door is started upward its removal is greatly facilitated. The converging side edges of the door are also ohatnfered off or beveled, as indicated at 2, leaving the door Wider at its front side than at the inside. To

' ,receive and hold the door, keepers 3 are artionally engage the chainfered edges 2 of the door, so that as the door is moved downward into placeitwill be crowdedagainstthe inner surface of thecar side or against the doorpost-s, asthe case may be.

'At their upper ends the keepers 3 are provided with horizontal restsv or flanges 6, eX- tending in opposite directions therefrom and provided with vertical openings 7, the purpose of which will, hereinafter appear. door l is provided on its upper edge'and .at each side with'metal plates 8, and pivotally mounted on each of said plates is a lockinglever 9. These locking-levers are arranged at each side of the door and are adapted to be swung outward, s o'as to extend inopposite directions and move onto thehorizontal rests or flanges 6.' VAt each side of the dooropening and located above the flanges 6 are Vbrackets 10, provid'edat top and bottom with horizontal extensions; 1l and 12, through Whichpass locking bolts or pins 13p'rovided at their upper ends with heads 14, whereby they'inay be turned, thesaid bolts having a threaded engagement with said brackets, so that when turned their lower ends 1may be moved downward 'and causedto enter the openings 7 in the ianges 6, above referred to. The locking-levers are provided intermediate their ends with inclined surfaces l5, which engage beneath the correspondingly-inclined lower ends of the brackets lO. rlhe relation of the locking-levers and locking-bolts is such that when said levers are moved outward, as shown in Fig. l, and the locking-bolts moved downward said bolts will confine the lockinglevers betweenthem and the side of the car, thus preventing any movement of said levers and rendering itinipossible for the doorV to keepers 3 are beveled so as to firmly and fric-V The IOC)

get loose or become displaced. By moving the bolts 13 upward the locking-levers il may be rocked inward toward each other and from beneath the brackets 10, after which the door may be moved upward and taken out.

Upon its inner side the door 1 is provided at each side edge with a cleat 16, the outer edge of which is rabbeted, as at 17, to embrace the inner edge of the adjacent keeper 3, and these cleats, which also converge downwardly to correspond with the side edges of the door, are connected by a horizontal bar 1S, which serves to brace the cleats and also forms a handhold by which the door may be lifted. Along the bottom edge of the door extends a metal strip 19, the lower edge of which projects beneath the edge of the door and enters a grooved plate 20, set into the fioor of the car so as to be fiush therewith, the plate 19 thus forming a cut-off for preventing grain from getting under the bottom edge of the door. \Vear-plates 21 are secured to the bottom edge of the door, at each side, and the chamfered side edges of the door are protected by strips of sheet meta 22, which are bent around such chamfered edges and eX- tended inward a short distance upon the outside and inside of the door, the extreme edges of the strip being bent inward toward each other and embedded in the door, as indicated at 23. It will thus be seen that the door, which is preferably made of wood, is thoroughly protected and reinforced upon all its edges, and that it is a matter of impossibility for grain to escape around the side edges of the door or beneath the bottom edge thereof.

The door is provided in its outer side with metal hand-lifts 24, which are set into the door so as to be flush therewith and recessed, as at 25, to admit the fingers. They are further recessed, as indicated at 2G, to admit the end of a pry for starting the door upward should it become stuck.

At a convenient point within the car, and preferably adjacent to the door-opening on one side, other keepers .T are provided for holding the door when the same is not required for use, Other sets of brackets ldand lock-bolts 13 may be provided at this pointv for engaging the locking-levers 9, and thus the door, when not in use, maybe held firmly .where it will be out of the way until again needed.

It will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having thus 'described the invention, what is claimed as new is- 1. The combination of fixed keepers provided at their upper ends with horizontal rigid flanges, stationary brackets arranged above said flanges, and spaced vertically with relation thereto, to leave openings between said brackets and said flanges, a door fitted slidably between said brackets, locking-levers fulcrumed on, and carried by, said door and adapted to be swung horizontally to occupy the spaces between said brackets and the keeper-flanges, and vertically-adj usted locking rods or pins carried by said brackets and arranged to be projected across the levers to confine the latterin their locked positions, as and for the purposes described.

2. The combination with fixed keepers and a slidable door, of brackets fastened above, and spaced vertically with relation to said keepers, locking-levers fulcrumed on, and carried by, said door,and provided with wedge or cam formed faces arranged to have wedgin g engagement with said brackets, and locking devices carried by the brackets to have fixed engagement with the keepers and to confine the locking-levers against displacement beneath the brackets, as and for the purposes described.

3. A vertically-sliding grain-door, in combination with locking-levers fulcrumed on vertical axes on the' top edge of the door at opposite sides and provided with inclined su rfaces, as described, stationary brackets on the ear-body having inclined portions for engagement with said levers, and locking bolts mounted in said brackets and adapted to engage said levers, substantially as described.

4. A sliding grain-door, in combination with spaced keepers between which the door slides, horizontal flanges at the upper ends of said keepers having vertical openings as described, locking -levers pivotally connected to said door at opposite sides, stationary brackets on the car-body arranged above said flanges, the locking-levers being movable between said flanges and brackets, and vertically-movable locking-bolts mounted in said brackets and adapted to engage the openings in said flanges, substantially as described.

In testimony that I clailn the foregoing as my own I have hereto afxed my signature in the presence of two witnesses.

HARRY MURRY TYRRELL.
